>> pelley: good evening. when a celebrity known to virtually everyone dies suddenly, so it was today with robin williams, dominating our national conversation, as everyone from the president to hollywood stars to just plain fans shared their thought, remembered the comedy routines they loved, and the movies they liked the best. williams' battle with depression was well known. today, the sheriff's department in marin county, california, confirmed that williams did commit suicide, and they told us how it happened. here's john blackstone. >> reporter: onein williams was last alive 10:30 sunday night. lieutenant keith boyd is the assistant deputy corner. >> it is not known at this time when mr. williams retired for the evening but he went to a different room of the home. >> reporter: just before noon monday, his personal assistant

entered his room and immediately called 911. >> the caller was distraught and indicated at that time that it was an apparent suicide due to a hanging had taken place and that rig mortise had set in. >> reporter: emergency responders found a belt around williams' neck, superficial cuts on his wrist and a pocket knife nearby. >> superficial wounds were not the preliminary cause of death. the preliminary calls of death is asphyxia due to hanging. >> reporter: on the hollywood walk of fame a wreath was laid on williams' star today. >> we made a costume change. >> reporter: one of his closest friends, billy crystal, posted this, "no words." lewis black costarred with robin williams in "man of the year." >> the opportunity to be in the presence of brill yaps, you're lucky when that happens and the fact that he was willing to share that with me was-- was very important. >> reporter: last month, williams checked into a rehab clinic that focused on sobriety.

he had just finished a string of projects. you're still in shock. >> yeah, i think so. >> reporter: bob sarlatte started in stand-up comedy beside williams. he sometimes hear the roots of comedy are in pain. was that true with robin williams? >> he would always come back and finish strok strong. he was working with that pressure. i think along with that pressure came maybe this sort of depression of the highs and lows. after you've won big like he dthere's nowhere else to go. >> reporter: the sheriff's department refuses to say whether or not williams left a note. the final corner's report confirming the cause of death has to wait until toxicology results are in. scott, that could take 2-6 weeks. >> pelley: williams was remembered today in washington by the national portrait gallery, which paint of picture of america through the people who shape our history and culture. the galilee put this photograph on display today. it was shot for "time" magazine by michael dressler in 1979.

williams' death is the second this year of a great actor who battled addiction. phillip seymour hoffman died in february of an accidental heroine overdose. jim axelrod tells us death of williams has, again, turned the spotlight on addiction, depression, and suicide. >> reporter: from the moment news broke of robin williams' suicide-- >> hello, life night, how can i help you? >> reporter: the phones started ringing at the national suicide prevention lifeline, and thigh haven't stopped. the last 24 hours has seen the second highest volume of calls in the past 12 months. lisa furst is the director of policy and education. >> whenever there is a public completion of suicide, it spurs people to reach out, especially if they didn't know where to reach out before, as many people may not. >> reporter: the most recent numbers from the centers for disease control show more than 39,000 suicide each year. that's an average of 108 each

day. dr. jeffrey borenstein is president of the brain and behavior research foundation. >> more people die from suicide than from homicide in the united states which is an amazing fact. most people don't realize how common it is. >> reporter: upon somewhere between a quarter and a third of people who die by sued are a substance abuse disorder. >> i went to rehab in wine country just to keep my option open. >> reporter: while he joked about it, kid wil' suicide underscores this wings between depression and substance abuse. addicts have a rate of sued three to four times higher than the general public. williams was candid about his alcoholism. last summer he described to jon stewart how easy 20 years of sobriety... >> the moment i had the first sip it was like-- whooooaa! it was like welcome back ( bleep ). >> if you only treat the

depression without treating the chemical dependency, you won't be successful in really helping the person. >> reporter: and probably won't be effective in dealing with either. >> neither of them will get better. >> reporter: we mentioned that today of the second busiest day at the suicide prevention lifeline. number one was a day in late may which was likely related to memorial day. >> pelley: always someone to reach out to, always. jim, thanks very much. today, east got a taste of what the midwest went through last night. the rain is coming down hard, and the floodwaters are rising quickly. how are folks coping? chip reid found out. >> reporter: this is what drives coped with in the washington area today, three inches of rain falling in one hour in parts of maryland. joy lieninger's car was almost swallow by rising waters. rescue teams had to float her to safety. >> it was very scary, sitting there in the car watching water get higher and higher. i'm so glad they came.

there had been concern that after eight years, he would try to hold on to power by military force. also, correspondent david martin is telling us tonight that president obama is sending 100 more american military advisers to iraq. 250 are there already. they're helping the iraqi government roll back isis, a muslim extremist army that has taken part of iraq and syria. president obama ordered airstrikes on isis when it threatened the kurdish city of erbil. that's where the additional american advisers will be going to help thousands of refugees who are surrounded on mount sinjar. yesterday, we showed you a mission to help those refugees after a helicopter dropped water, some of the refugees seized the chance and jumped aboard. well, today, a similar iraqi mission crashed after it, too, was rushed. the pilot was killed. many were injured.

refugees are fleeing because ice militants have murdered by the thousands anyone who is not a member of their sunni muslim faith. holly williams discovered what's happening to the christians. >> reporter: christians have lived in bartella for at least 1500 years, and we found them still praying in aramaic, the language spoke bien christ. we visited the town two months ago as isis militants began their campaign of violence and terror in northern iraq. with islamic extremists just 10 miles away, captain firaz jacob and his 600 local militiamen had vowed to protect their homes. if the militants come here to this christian town what will they do? "we don't know," captain firaz told us. "but may be they'll do what they

did in other places and kill us." they held on until last week when isis went on the rampage again, capturing more territory for what they say is their own islamic state. the townspeople fled in the middle of the night. now 200 families are crowded into this community hall, including marbel, who was born the same day they ran for their lives. these are proud people who have lost everything and have nowhere to go. captain firaz is here and told us he was the last to leave bartella after everyone else had made it out. do you think utility ever be able to go back to bartella? "if we go back to our town in a few months or a few years, we'll be pushed out again. we need somewhere safe to live." >> pelley: and holly williams is joining us from erbil. holly, we mentioned a moment ago, that the current prime

minister, nouri al-maliki, is on his way out. how did that happen? >> reporter: well, many people blame al-maliki for fueling religious and ethnic tensions here. he's now isolated and will probably have to leave office. he's also lost the support of his iranian backers, as well as the militia that were once loyal to him. but, scott, the question is whether eye new government can end those hatreds and unify iraq. >iraq. >> pelley: a far way to go. holly williams for us in err being. thank you very much. and on that point, we'll turn now to michael morell, who until last year was number two at the c.i.a. he's now a cbs news consultant. mr. morrell, does changing the government in baghdad mean this civil war can end? >> scott, prime minister maliki was the biggest source of the problem. he was more responsible than anybody else for isis' rise. his disenfranchisement of the sunnis in iraq led them to support isis. so moving on to a new government

that can bring the kurds, the sunnis and shia together create a real opportunity for the government to take on isis in full force. >> pelley: you have called isis a terrorist army. how do you deal with that in the long term? >> i think there are two things that have to be done. one is very top leadership has to be removed from the battlefield. the second thing that has to happen is the iraqi military has to take on isis as a military on the battle field, and now that been a political solution in baghdad or the appearance of at least a political solution in baghdad, we have a chance to get the iraqi army back together and moving again. >> pelley: michael morell, former deputy director of the c.i.a., thank you. today, canada said it will offer an experimental ebola vaccine to patients in africa. canada has about 1500 doses available but it's not known if the drug will work. today a spanish priest who had been given the drug died after

with the all-white police force in this largely black community had not been much of an issue before saturday but this week's anger is fueled by mistrust and the methodical by the book police investigation into saturday's broad daylight shooting of michael brown. the unarmed 18-year-old was stopped initially for walking in the street but wound up being shot repeatedly by a white officer. >> there was a struggle inside the officer's car, and there was an additional struggle outside of the car. >> reporter: but a friend said brown had his hands up when he was killed. the officer's name has not been released because police fear retribution. >> i don't think he had a problem with my son. i think he has a problem with himself. >> reporter: we spoke with lesley mcspadden, michael brown's mother. what would you say to this police officer? >> you know what i would say to him? the same thing i would say to my

son if he did something wrong and he know he did something wrongue take your punishment. and if you a man, you stand up and you be a man. you say, "i was wrong." that's how we was taught. when you're wrong, you're wrong. >> reporter: michael brown's mother also told us she is deeply concerned about the violence that has come after her son's death, saying she feels fought between the protesters and the police. and once again, today, scott, she called for calm. >> pelley: dean reynolds in ferguson for us this evening. thank you, dean. today in a lightning-fast robbery, eight gunmen stole $10 million from an armored truck at the airport in santiago, chile. this is said to be the largest heist in chile's history. do not adjust your set. those really are panda triplets,
